The Iranian constitution calls for a Presidential election once every four years (in practice, the year following Presidential elections in the United States). Candidates are selected by the [[Guardian Council]], an unelected clerical body. Presidents are limited to two terms as in the United States. While since 1981 no Iranian President has been defeated for reelection, elections lacking an incumbent have been quite lively, as was the 2005 election, which Ahmadinejad only won at the runoff stage. | The Iranian constitution calls for a Presidential election once every four years (in practice, the year following Presidential elections in the United States).
